Any suggestions about PCB finish for RoHS

2017/2/28 8:45:08

Hi all, I am wondering what everyone is using as a PCB finish for RoHS. There doesn't seem to be a favorite out there. I know there are many companies using a gold finish but I don't want to pay that much and I have also heard about reliability problems with soldering to gold. We are currently using Immersion Sn but are having problems soldering after the board has been through a reflow oven. I am looking into a Pb-free HASL. Does anyone have any suggestions?

Your help will be appreciated.

Thanks.
